Mrs. T over at Fistful of Euros tried to explain the "overhanging mandates" situation and why the CDU winning the delayed Dresden I elections (a local neo-Nazi candidate died, thus derailing the legalities for that district, and forced a delayed vote) might actually cause the CDU to *lose* a seat. I read the post twice, and I still don't understand the exact mechanism, but then I never was any good at higher math. I'm now regretting my failure to take calculus in school - I suspect it might have come in handy right about now.
The Germans no longer get to make fun of the American electoral college. This "overhanging mandate" business is deranged.
